Fixed in 2.0 using the JexlEngine.setLenient(false) method.

> Currently JEXL is very tolerant with null (and unresolved variables)... 
> I am unsure now but I think null will become false if the output of a test, null will
become the empty 
> string if concatenated to a string, null will become the number zero when added. Moreover,

> invoking a method on null gives you... null...
> I would love a switch that just disables all this (I think this would impact quite a
lot) allowing my jexl 
> snippets to be quite more predictable!
